We analyze how the possibility of resale affects efficiency in multi-object uniform-price auctions with asymmetric bidders using a combination of theory and experiments. The resale market is modeled as an unstructured bargaining game between auction bidders. Our experimental design consists of...

When a seller gives a buyer a right of first refusal, although it reduces the competing buyers' profits and creates an inefficiency, it always increases the joint profit of the seller and the right holder. Right of first refusal with a consideration (e.g., a payment from the right holder to the...

This paper analyzes the secret reservation price in eBay auctions. Under the assumptions of secret and public reservation price, the bidders choose the optimal bidding function and the seller selects equilibrium reservation price. This model argues that the choice of secret reservation price is...

We examine a model in which multiple buyers with single-unit demand are faced with an infinite sequence of auctions. New buyers arrive on the market probabilistically, and are each endowed with a constant private value. Moreover, objects also arrive on the market at random times, so the number...

A bidder may increase his bid over the course of an auction when (1) he becomes more certain about his private valuation over time (as he has more time to consider using the item), and (2) there is a positive probability he is unable to return to the auction to submit a bid in a later period.

We develop a model of a dynamic market with randomly arriving participants. Both buyers and sellers arrive probabilistically over time. The valuation of each buyer for each object is independently distributed and private information to each buyer. Equilibrium prices are determined by a sequence...

This paper evaluates performance of human subjects and instances of a bidding model that interact in continuous-time double auction experiments. Asks submitted by instances of the seller model ("automated sellers") maximize the seller's expected surplus relative to a heuristic belief function,...

Although bidders in an internet auction do not obtain the actual ownership of the item during the auction, they still act according to an endowment effect. In a unique data set of 17,000 Danish furniture auctions I find that having the leading bid, both in terms of time and dollars, will...

A classic argument in economics is that experience in the market place will eliminate mistakes and cognitive biases. Internet auctions are a popular market were some bidders gather extensive experience. In a unique data set from a Scandinavian auction site I question if and what bidders learn....

Most internet auction sites, like eBay, use a proxy bidding system where bidders can put in their maximum bid and let a proxy bidder (a computer) bid for them. Yet many bidders speculate about how to bid and employ bidding strategies. This paper examines how the timing of bids can affect the...
